GRAIN-BINDER.

useful Improvements in Grain-Binders, of

which the following is a specification.

. This invention relates to grain binders,

and it has particularreferen'ce to an improved draft attachment.

It is customaryin grain binders to conmeet the tongue with the frame" ofthe machine in advance of the bull wheel and relatively near the bindersideof the machine.

Sometimes the condition of the grain is such that the cutting apparatusis subjected to a peculiar and excessive strain in which event thecutting side of the machine is apt to sag behind. At other times, thecondition of the grain is such as to particularly tax the bindingmechanism in which event the binder side of the machine will sag behind.

The present invention has for its object to produce a simple andeffective draft attachment which shall be connected with parts of thebinder frame adjacent to the binding side and the cutting side,respectively, to enable both sides to be subjected to the draft.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claim.

In the accompanying drawing has been illustrated a sim le and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,

; but that changes, alterations and modifications within the scope ofthe claim may be resorted to when desired.

In the drawing, Figure 1 is a top plan view of a draft attachmentconstructed in accordance with the invention. Fig. 2 is a side elevationof the same. Fig. 3 is a sectional detail view taken on the line 33 in.ig. 1. Fig. 41 is a perspective view showing the evener bar 6 detached.

Corresponding parts in the several figures are denoted by likecharacters of reference.

of the latter by means of a hinge bolt 2 upon which the tongue may swingfor adjustment in an approximately vertical plane. The tongue 1 isconnected with the binder frame relativelynear the cutting side of thelatter by means of a brace 3 which likewise has a hinge connection withthe frame by A bar 6 which constitutes an evener is pivoted on thetongue l'by means of .a pin or bolt 7.

The evener bar 6 .hasdat its outer end a shoulder or offset 8 and arearwardly offset portion 9, said offset portion being provided with aseries ofapertures 10.

l1 designates a bell crank, one arm of which is bifurcated, as shown at12, while the other arm is provided with a series of apertures 13corresponding with the apertures 10 in the offset portion 9 of theevener bar with which the said bell crank is ad justably connected bymeans of a pin or bolt 14. The bolt '14: is connected by a brace rod 15with the eye or member 5 on the binder frame with which the rear end ofthe brace 3 is also connected. The brace rod 15 includes a turn buckle15, enabling the length of said brace rod to be varied to compensate forvarious adjustments of the bolt 14. The brace rod 15 extends across thetongue 1 on which it is supported, thereby supporting the evener bar 6and related parts approximately in the plane of the tongue andpreventing said parts from sagtured limb of the bell crank is connected1 by a brace 16 with the pin or bolt 2 by which the tongue 1 isconnected with the binder frame. The bifurcated arm 12 of the bell crankis adapted .to receive an ordinary draft equalizer whereby draft isapplied to the machine.

As will be seen from the foregoing description, the tongue 1 and thebrace 16 are connected with the binder frame relatively near the bindingside, while the braces 3 and 15 are connected with the machinerelatively near the cutting side. By shifting the location of the bellcrank 11 relatively to the evener bar 6, the preponderance of draft maybe shifted in the direction ofthe binding side or the cutting side, asmay be required, the requisite adjustment being easily effected bysimply removing the bolt 14 and replacing the same after adjustment ofthe parts.

The device is simple'in construction, easilyin'stalled, efiective inoperation, and it will not interfere with the adjustment of the tonguerelatively to the binder frame which is necessary for the purpose ofef-. fecting proper adjustment of the cutting apparatus. a
